Grade 43 high carbon steel chains provide higher tensile strength and greater wear resistance than Grade 30 chains. The chain is manufactured to NACM standards. Each link is proof tested two times and the break load is 3 times the Safe Workload (design factor 3:1). Grade 43 chain is recommended for applications that do require higher strength-to-weight ratios. It is a better choice for heavy duty trucking, towing, logging, and more demanding construction activities. Chain is zinc plated for a bright, attractive finish with moderate corrosion resistance. Do not use for overhead lifting. Never exceed the Safe Working Load (SWL).
